move to libxsc: net init 3: actual move

Reincarnate gsm_network_init() as the parts not specific to libbsc.
Move from bsc_network_init() those bits that are not BSC specific (and useful
for upcoming osmo-cscn).

Add libxsc to all linkages that use gsm_network_init().

Note: the only requirement to allow linking gsm_network_init() without libbsc
is to keep the call to gsm_net_update_ctype() out of libxsc. The other items
are kept out of libxsc because it makes sense semantically. But the separation
is not strong in that the BSC specific data members are of course still
omnipresent in struct gsm_network. If bsc_network_init() is not called, these
are not initialized properly -- for now no users of uninitialized members
exist.

So this is just a first step towards a sensible split of the BSC and MSC
gsm_network structs. The long term aim should be to have entirely separate
structs with some common general items.
